Brake Control Device for Mobile Object Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile objects with attached drive units, such as pallet trucks, face challenges in safely stopping the object, particularly when unintended traveling occurs.
Innovation Solution
A brake control device is introduced, featuring an operating switch that turns on when operated by a user and turns off when released. The control device executes first brake processing when the switch is released during travel, ensuring the mobile object can be appropriately stopped.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the electric motor outputs assist force depending on acceleration to enhance mobile object performance, then the mobile object can start moving when a user leans against it or is disposed on a slope, but unintended traveling of the mobile object occurs
Solution Approach 1:
The brake control device applies preliminary anti-action by automatically executing brake processing when the operating switch is released during traveling. This preventive measure counteracts the unintended traveling caused by the assist force mechanism, ensuring the mobile object stops reliably even when acceleration-based assist force is active
2Ease of operation
If the operating switch is released from being operated by the user, then the user can release control of the mobile object, but the mobile object cannot stop appropriately in case of unintended traveling
Solution Approach 1:
The brake control device implements feedback by continuously monitoring the state of the operating switch and automatically triggering brake processing when the switch is released during traveling. This closed-loop control ensures that releasing the operating switch results in automatic stopping, maintaining both ease of operation and stopping reliability

AI summary
A brake control device includes an operating switch and a control part. The operating switch is configured to be turned on when operated by a user. The operating switch is configured to be turned off when released from being operated by the user. The control part executes first brake processing for stopping the mobile object when the operating switch is switched off from on during traveling of a mobile object.
